So maybe, that's what it is.. If true, Mark must be having some sort of pain in his arm - and enough of it to actually need this kind of medical attention?.

I see..I have a TENS unit. I dont used it. Because its pain in the butt. It's sorta like walkie talkie. You clip on your pants or belt. Whatever clothes your wearing. You put thes patches on your back. Then hook the wires to the patches..turn the dial just so. Which one feels comfortable to you. I used wear it, 4 30 mins or 60 mins. (then, I take it off.) Then, i have turn the dial. But, if i moved..the dial turns up on its own.

I have pain in my back, hip, knees, legs, ankles & sometimes arms..I have arthritis in my right hip & both of my knees.

Now, Mark's unit is cool. Looks like he just peel & stick it on his arm..Go about his business.

His unit, I wonder, if its his just for his arms or for his whole body. (If, it's whole body. that's so cool.)

My TENS Unit company is Century2100

Wonder, what company Mark's TENS units is?

Do they make a TENS Units for the whole body?

Because, my knee is really bad. Sometimes, I'll be sitting in a chair or laying in bed. My right knee will just twitch on me. I wouldn't be do nothing. My arthritis in my knees, are getting worse. My back is getting worse. I take pain meds for it.

OH yeaah, guess what, just because we're on the topic of place/weather and things. My Mum is currently in America! In Salem, Portland I think? That's the southern part of North America right?_________________
